Some regions of the oral cavity present anatomical conditions that seem to hinder the result of gingival recessions coverage. Thus, the aim of this case report was to present two surgeries for gingival recessions coverage in the mandibular teeth performed on the same patient with the follow-up of 24 months. Patient RP, 35 years old, male, Caucasian, nonsmoker, systemically healthy, sought care at the clinic of specialization course in Periodontics from the Araraquara Dental School (Foar-Unesp). His main complaint was the gingival recessions within the lower teeth 33, 34, 35, 43, 44 and 45. Besides the aesthetic nuisance, the patient reported occasional dentin sensitivity. For resolution of the case was referred to the technique of subepithelial connective tissue graft associated with a coronally advanced flap. After 2 years of surgery, it was observed an excellent root guards with significant aesthetic improvement of the case. It can be concluded that the subepithelial connective tissue graft technique was effective in covering of type class I gingival recessions of Miller, even in a region that provides a difficult procedure.

A catarata é a afecção da lente mais comum em cão, caracterizada por uma opacidade do cristalino e alteração de comportamento devido ao déficit visual. O exame oftálmico adequado e completo da lente permite a classificação adequada da catarata auxiliando na escolha do melhor tratamento de cada paciente. O tratamento preconizado para a catarata é o procedimento cirúrgico, que associado com o uso de anti-inflamatórios, midriáticos e antibióticos pré-operatórios e pós-operatórios melhoram os resultados visuais e previnem algumas complicações. A remoção da lente pode ser feita pelas técnicas de discisão, extração intracapsular, extração extracapsular e facoemulsificação, sendo que a escolha correta da técnica para cada caso contribui para o sucesso do procedimento e diminui as complicações pós-operatórias, porém as técnicas de escolha para a remoção da catarata são a extração extracapsular e a facoemulsificação. O objetivo da revisão sistemática é comparar as complicações de duas das técnicas para extração da catarata, extração extracapsular e facoemulcificação, ressaltando qual a técnica que apresentou menores complicações em cães. Foram analisados dez artigos pesquisados nas bases de dado PubMed e Google Acadêmico, sendo complementados com o uso de livros. Foram encontradas como complicações perda da visão, glaucoma, descolamento de retina, hemorragia intraocular, ruptura da cápsula posterior, alterações corneanas, endoftalmites, sinéquia posterior, fotofobia, blefaroespasmo e hiperemia conjuntiva. Essas complicações foram descritas em ambas as técnicas, porém inúmeros fatores

An experimental study was undertaken in arder to find out lhe behavior of the required force to yield dislodgement of circumierential clasps of removable partial dentures ou two groups of samples. 1 with retentive terminais engaging and acting ou enamel 2 with retentive terminais engaging on enamel and acting on composite resm With this aim a device was designed based on a sewing machine (brand name Elgin) that could repeatedly simulate lhe introduction-removal movement of circunferencial clasps ou the samples. ln addiction the device had a platform to sustain the samples and permit measurements, a cycle counter and a dynamometer. The samples were constructed by inclusion in dental stone of extracted natural molar teeth whose retentive areas were ou natural enamel or composite resin addictions.The clasps were fabricated from wax ups of resin and wax and were cast with chromium cobalt alloy. The composite resin used was one of the last generation, monomodal type, photopolymerized and binded to the enamel by the acid etching technique. Tests were carried out in aqueous enviroment. Is was established a maximum of 5.000 cycles for each of the samples. Observatins were made from 100 to 100 cycles until 2.000 and from 200 to 200 cycles to 5.000. Results showed that variations in the amount of the required force for dislodgement of the clasps from the samples during the test periods had no significancy eather to those with retentive areas on the enamel or to those with retentive fabricated with addictions of composite resin

The tooth eruption have been studied for many years about the knowledge of its variations. From these variations the difference between the eruption of the superior and inferior archs, and also the right and left sides have been poorly analysed. The author compared the alveolar eruption of the permanents canines, first and second premolars between the right and left sides of the superior and inferior archs, from 7 and 11 years of age, in males and females, by radiographic method. By the Discipline of Radiology of the Diagnosis and surgery Departament of the School of Dentistry of São José dos Campos - UNESP, observed that: there is early eruption in female; the alveolar eruption sequence in maxillar and mandibular was: first premolar, second premolar e canino. There wasn't statiscally significant difference of the alveolar eruption between the right and left sides of maxillar and mandibular archs
